Hello Dave,

1. There is a 5V supply on ther grey RJ48 connector but it is not normally accessible because we use a 8-core cable instead of 10-core cable. This is to protect against excessive current drawn by an external device abd affect the performance of the controller. There is only 10mA available before the 5V regulator warms up too much. If you want to access this source, a 10-core cable has to be crimped into the 10-way RJ48 plug. Let me know if you want us to supply this with the system.

2. This is a good use of water/mthhanol injection. It is more commoin for the system to replace race fuel with pump fuel. I cannot see any reason why this can't be achieved. The HFS-4 is well equipped to do this job, tracking fuel flow from medium load to high. I would say yes.
